Peparation of Chloroform From carbon tetrachloride
Now-a-days, chloroform is obtained on a large scale by the reduction of carbon tetrachloride with iron fillings and water.
This chloroform is not pure and used mainly as a solvent.
(iii) Pure Chloroform is obtained by distilling chloral hydrate with concentrated sodium hydroxide solution.
Chloral hydrate is a stable compound inspite of the fact that -OH two groups are
linked to the same carbon atom. This is due to the fact that
intramolecular hydrogen bonding exists in the molecule between chlorine and
hydrogen atom of -OH group.
